Hendon (NW4) in Barnet ranges from the historic Church End village around St Mary's church to streets of Victorian and interwar houses, and the usual brief is a rear or side extension or a loft conversion to add family space.

The Hendon Church End conservation area protects the medieval church core, its listed buildings and the hilltop views, so if your home sits inside the boundary we check it first and steer massing and materials before deciding between permitted development and a full householder application.

Planning in Hendon (NW4): what to know before you apply

Across the wider NW4 suburb, rear extensions and loft conversions typically proceed under permitted development or a lawful-development certificate. Inside the Church End conservation area, or near the listed buildings around St Mary's, expect a full householder application with attention to setting and skyline.

Planning Drawings for Hendon (NW4) homes: the package and the process

Every planning drawings we prepare for an Hendon property is drawn to London Borough of Barnet’s validation standards and tuned to the NW4 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

Planning drawings are the scale drawings a London council uses to judge your application: existing and proposed floor plans, elevations, sections and site plans that show the design, scale and neighbour impact of your project. DrawingsDirect produces complete, validation-ready planning drawing sets for extensions, lofts and conversions across London.

What is included in a planning drawing set?

A council will only validate an application that contains the right drawings at the right scale. Our standard planning set covers everything a London validation team expects.

  • Site location plan (1:1250) and block plan (1:500)
  • Existing floor plans, elevations and sections
  • Proposed floor plans, elevations and sections
  • Roof plans where relevant, with heights and materials annotated
  • A design and access or heritage statement where the borough requires one

How are planning drawings different from building regulations drawings?

Planning drawings show what the building will look like and how it sits in its context. Building regulations drawings show how it will be built safely — structure, insulation, fire escape and drainage. Most projects need both; our Complete package covers the two together with structural calculations coordinated in-house.

FAQ

Planning Drawings in Hendon NW4 — FAQs

What scale should London planning drawings be?+
Site location plans are 1:1250, block plans 1:500, and floor plans, elevations and sections are typically 1:100 or 1:50. We format every drawing to your specific borough's requirements.
Do I need an architect to produce planning drawings?+
No. MCIAT-chartered architectural technologists produce the same council-accepted planning drawings with the same professional accountability, and councils assess the drawings, not the author's job title.
How many revisions are included in the fee?+
All of them. The fee is fixed and we redraw free until your council approves — revisions requested by a planning officer never cost you extra.
Can you draw from my existing plans?+
We can work from existing measured drawings, but for accuracy we usually carry out a laser survey so the proposed set matches your property exactly.
Do planning drawings guarantee approval?+
No drawing can guarantee a decision, but drawing to the local plan and validation checklist maximises your odds — and we redraw free until approval.
Do I need planning permission for a loft or extension in Barnet?+
Across Finchley, Edgware and Hendon, Barnet's 1930s semis usually keep permitted development rights for rear extensions and hip-to-gable or dormer lofts, so a full application isn't always needed. The major exception is Hampstead Garden Suburb, where an Article 4 direction removes almost all permitted development rights. We check your address first and confirm permitted development with a Lawful Development Certificate where it applies.
What is different about building in Hampstead Garden Suburb?+
The Suburb has one of the most far-reaching Article 4 directions in London: almost all external alterations need planning permission, and the Hampstead Garden Suburb Trust must also consent to changes in parallel with the council. We handle both tracks — a carefully evidenced planning application to Barnet and the Trust's design requirements — since approval there depends on respecting the Arts-and-Crafts character precisely.
Is a hip-to-gable loft conversion allowed on my Barnet semi?+
Usually, yes. The borough's abundant interwar semis are well suited to hip-to-gable and dormer conversions, which frequently qualify as permitted development on semi-detached homes within the volume limits. Outside conservation areas and the Suburb, this is often the quickest route. We confirm eligibility, then produce the planning and building-regulations drawings.
How long does Barnet take to decide an application?+
Barnet determines most householder applications within the statutory eight-week period once validated; Suburb and conservation cases can involve additional consultation. We prepare Barnet submissions to the validation checklist, with the elevations and materials detail the council expects, to avoid the drawing queries that are the usual cause of delay.
How much do Barnet planning drawings cost?+
We agree a fixed fee before we start, typically around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Barnet approves. A straightforward Finchley loft and a Hampstead Garden Suburb application differ in the evidence required, so we quote once we have seen the project and know which route applies.
